Blocky saysERC-1155 is a multi-token standard — one contract managing many fungible and non-fungible items.
ERC-1155 lets a single contract hold many token types at once — fungible (gold coins), non-fungible (a unique sword), or semi-fungible — with efficient batch transfers. It's ideal for games and marketplaces with thousands of item types, saving gas and deployment overhead versus a separate ERC-20/721 contract per item.
